Abstract
The Environmental Protection Agency (EPA) is taking direct final action to adjust the reportable quantity (RQ) for Isophorone Diisocyanate (IPDI). Reportable quantities for many Extremely Hazardous Substances (EHS) under the Emergency Planning and Community Right-to- Know Act (EPCRA) were adjusted to their threshold planning quantities (TPQ) in a final rule on May 7, 1996. On September 8, 2003, EPA modified the TPQ for IPDI to 500 pounds. However, EPA inadvertently omitted an RQ adjustment for this substance. Therefore, EPA is now adjusting the RQ for IPDI to be 500 pounds.
